A i .citizen of the United States, residing at New 'York, inthe -county of New York andState of New York, have invented. new anduse-ul Improvements in Signals, of. whichthe following is a specification.

- vide an improved arrangement for effecting- A principal object of the invention is to produce'a signalwhich canbe operated in y the ordinary way by hand, but which is` associated with electrically controlled means forj independently actuating the whistle.V

` vkA further objectof the inventionis to provide Aautoma-tic meansl independent of the'ordinary hand operated mechanism forenabling the whistle to be sounded periodil' cally;y i, i A'urther object lof the invention is to pro# the automatic sounding; of the lwhistle at regular' time intervals fby, electrical Ameans avoiding the necessity for a-spec1ally constructed clock motor.

` A further` object of the invention is to pro; Y vide an arrangement enabling the whistle` Vto be controlled from-.several points, -or exi' and combinations of'parts to be`---\de scribedy ample, as on board'sh-ip, where such an arrangement enables the whistle to Vbe con-A pilot house and from bothtrolled-from the `ends of the bridge.

l -tion throughthe switch box illustrating the' 10 represents a whistle .or other signal of A any sui-table form'which may be duid-operated, or, which' purpose the pipe Aconnection `10aiupon 'which the whistle is :attachedis provided with valve means 11 includin'gaA jdislgA valve normally held 'on its seatv by a spring 12. This valve 11 isf operated!eitherA manually or electric-ally, but is vadapted to l be opened by steam pressure which-is adapted to enter into the outer end.ofthe. steam chamber 14 1n which moves an actuator pretv erably-in theform. of a piston 13, said pist-on having ajstem j15 which passes' through the end wall-for head .16 of the chamber.

The end of this stem '15` rests against the faceof the. valve'll so that if the steam or other fluid vis admittedto the chamber ythrough port 20, the valve 11`v`vill open and A valve'having astem 19-which extends longi' tudin'ally along the side of the case 22, being lguided in" suitable lugs llasothiat the outer'- end'ofrsaid'stem lits adjacentto the short arm of a hmdopei` ated` lever '24,* said lever having its fulcrurr on 'the' post 23 at the' outer head 37 'of the case. The long arm of this lever is provided with a. cord 25' whichis connected with an ordinary vhand pulled' device to enable the-whjstle'tobe blown y at will.

l,In 'order to adapt the auxiliary valve 17 to' be opened by' j electrically L controlled means,I prefer. to form the case 22 injthe shape of 'a hollow cylinder, in the interior of which I place an electromagnet 26, preferably of the iron clad type, the lcoils of which within a metal shell 35. The case 2 2 is'pref- -permit steam `to flow ydirectly through port-V erablyV provided with screw threads 38 -en--1 abling it to be attached inthe end ofichamv` berl4. Mounted to slide/.in the inner end ofthe loc .are disposed around a suitable core 36, and

mature with a pin 28 which vfits neatly in a bore in the core 36, said bore carrying a spring 33 which moves the armature away from the magnet whenever themagnet becomes denergized. On the side of the armature away .from the magnet another guide pin 29 is formed which moves in a suitable drilled hole in the inner head of the case. Pivotally attached loosely to the armature on its inner side there is a lever -30 having its fulcrum on a pin 30a, and beyond this pin 30?, the lever is formed with forks 31 which straddle the stem 19 and rest against the face of a collar 32 formed on this stem.

IVhen the magnet 26 is energized, evidently the armature 27 will be attracted and the forks 31 will move the stem 19 toward the left, as viewed in Fig. 1, and this will open the auxiliary valve 17 and opcrate the signal. Evidently the lever 24 or the lever 30 can operate the whistle independently of each other.

I shall now describe the means for controlling the circuit through the magnet 26, which circuit passes through the conductors 56 and 57 which are connected with the o-pposite ends of the magnet. For this pur` pose, I prefer to provide an arrangement such as that illustrated diagrammatically in Fig. 1. This apparatus is such asto enable the magnet to be operated at will, or if desired, it can be energized periodically by automatic mechanism, which automatic mechanism is also preferably controlled electrically. lAs such automatic mechanism. for operating whistles must operate to sound the whistle at regular time intervals to meet the marine rules, it is necessary to get substantially the effect of a clock mechanism. I accomplish this in a very simple way by providing an ordinary electric motor, and arranging apparatus to be driven from it in such a Way that the final driven shaft of the timing device rotates at a speed of one revolution per minute. lVith this arrangement, by placing a cam on this shaft, I can readily arrangeV to sound the Whistle once in a minute,'and by changing the length of the projecting face or cam tooth, I can readily change the length of time or number'of seconds during which the whistle Will sound.`

Such a motor as I describe is indicated diagrammatically at 49,` said motor having the shaft 51 and including suitable change speed mechanism, for driving the cam 50.

The cam 50 controlsa switch member 53 which closes the automatic circuit.

The energizingv of the magnet 26 may be controlled fromany number of points such as thel three points 39, 40 and 41. The point 39 is supposed to be in the pilot house or conning tower of the ship, or at any other point of control. The points 40 and 41 may cally closes the following circuit, which circuit energizes the electrom'agnet 26 and keeps the whistle sounding until the arm 42 l is moved again to mechanically open the Acircuit; double switch. 63 having been closed, the current passes in by the line Wire 62 through fuse 60 andconductors 59 and 48,

pivot 48a, vthence by arm 42 and contact 47v vto conductor 44 and conductor 56 through the coil of magnet 26 returning by the Wire 57 to 68 and thence by fuse 58 throughthe line wire 61.- If -the whistle is to be sounded automatically, the lever 76 is moved in the opposite direction, that is, toward the I left until contact 45 comes against contact V46. This will close `a second circuit; wireV 62 through switch 63, fuse 60, conductor 59,

vconductor '48,pivot42a, arm 42, contact 46,

conductor 43 and through43 to motor terr minal 69 and thence through the motor to motor terminal 66, and then by conductor 67 through 68 and the fuse 5 8 to Wire 6l'.

-This will start up the motor and will drive the cam 50;.whenever the vcam -tooth A52 shoves the switch lever 53 toward the right,

a second path for the current' will be formed around the motor, from the point 70 to contact 65, through. lever 53, conductor 73 to the point 72 and from this point by a conductorA 55 to 74; from 74 the current will pass along the 4conductor 56 'through theV electromagnet 26 and return by contact 57 to the point 68'and then' out to the line wire 61.

As shown in Fig. 4, the cover 39b indicate the proper direction of movement vof the lever 76.

I shall now describe the preferred construction and arrangement of the motor and the change speed mechanism for driving the timing device ofwhich the cam 50 forms a part.

The shaft 51 of the motor preferably carries a worm which meshes with a Worm wheel 86 on the shaft 87, and the shaft 87 carries a worm 88 which drivesa wormwheel 89 y on the shaft 90, said shaft 90 carrying the aforesaid cam 50 and being mounted at its outer end in a suitable bracket 91. vThe worms and worm shafts' `are arranged so that' Ithe-shaft 90 will make one revolution per minute. lWith this arrangement it will be evidentthat the length of the high cam face I52 will determine the length 'of time, or

number of seconds the whistle will sound,

and it will be evident. that by substituting.

cams ofV diiferent'kinds, any number of different lengths of time of sounding can be automatically given.

On the base 81 for the motor 64 and adi .jacent to 50, I provide thefswitclij-B' which ispivoted 'at 53 and normally'he'ld up by'an insulated spring 54-' so' .that the wheeli77 havingthree notches78, any one of .which 'may be-engaged by'a roller 7 9earried o`n af lever 80,v which lever ispivoted at f sparking, I prefer tojprovide auxiliary car.v -I

The switcharmj?) is, 'of course, insulated i in any suitable manner so" that when thev switch is closed the current passes in through 'the contact 73a and through platej-72a- -to conductor 73 and-.thenbyconnecting bolts v v53 .to the plates '65a and 65d.
